Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
Embodiments of the invention one as shown in Figure 1.With reference to figure 1, line is repaired loop and is mainly comprised line segment 21, line segment 22, line segment 23, line segment 24, line segment 25 and line segment 26, altogether latter linked line segment before six sections.Wherein, line segment 21, line segment 22, line segment 24, line segment 25, line segment 26 totally five sections be positioned on array base palte 12, line segment 23 is positioned on pcb board 13.
To walk line resistance in order reducing, line segment 21, line segment 22, line segment 24 to be all designed to by first layer metal and the stacking double-level-metal forming of second layer metal; Line segment 25 is designed to second layer metal, line segment 26 is designed to first layer metal; Data line 20 is second layer metal.
Walk line capacitance for reducing, line segment 21, line segment 22 are designed to suspension joint, and the line segment 22 of corresponding each data line drive circuit 16 is and disconnects design with line segment 21, only in the time that needs carry out line reparation, weld by the method for laser dotting again, lower line segment electricity is communicated with.
In the time there is disconnection defect on data line 20, carry out line defect reparation operation as shown in Figure 1:
K) 31 at line segment 21 locate to locate with 32, carry out laser cutting, between point 31 and point 32, cut out a line segment.
L) at point 34 places and point 35 places, carry out laser bonding, make line segment that invocation point 31 and point cut out between 32 respectively with line segment 22, data line 20 is realized electricity and is communicated with.
M) by after above operation, the signal of data line 20 will enter printed circuit board (PCB) 13 by line segment 22, after the amplifier 14 on printed circuit board (PCB) 13 amplifies, then by line segment 24, be input to array base palte below.
N) region overlapping with data line 20, the region overlapping with line segment 25 of the line segment 24 below array base palte, and line segment 26, carries out laser bonding processing, forms pad 36 and pad 37; On the right side of pad 36, line segment 24 is cut off, form breakpoint 33 simultaneously.
O) repair by above, the electric signal of data line, by line segment 25, line segment 26, is input to the following part of data line 20 breakpoints 100, thereby realizes broken string reparation.
On array base palte, connected by two line left and right, for each data line drive circuit IC, be the corresponding design in upper right, lower-left, as the IC1 to IC24 in Fig. 1, all same design.Therefore when actual repair, simple, identification is high.
Embodiments of the invention two as shown in Figure 2.With reference to figure 2, line is repaired loop and is mainly comprised line segment 41, line segment 42, line segment 43, line segment 44, line segment 45, line segment 46, altogether six sections of circuits.Its middle conductor 41, line segment 42, line segment 44, line segment 45, line segment 46 totally five sections be positioned on array base palte 62, line segment 43 is positioned on pcb board 63.
In order to reduce the line resistance of walking of repair line, line segment 41, line segment 42, line segment 44 are all designed to by first layer metal and the overlapping double-level-metal forming of second layer metal; Line segment 45 is that second layer metal, line segment 46 are first layer metal; Data line 70 is second layer metal.
Walk line capacitance for reducing, line segment 41, line segment 42 are designed to suspension joint, line segment 42 lines of each data line drive circuit IC66 and line segment 41 are and disconnect design, while only having the line of needs to repair, then weld connection.
Embodiment bis-is with the difference of embodiment mono-, and line segment 41 is for disconnecting design, and each data line drive circuit IC region as shown in Figure 2 all disconnects once.If there are 24 IC, be broken as altogether 24 sections.And IC1 to IC24, all same design, simple equally, identification is high, and compared with embodiment mono-, can save a laser cutting operation.
In the time that disconnection defect occurs data line 70, carry out line defect reparation operation as shown in Figure 2:
A) carry out laser bonding operation at point 51 and point 52 places, form pad 51 and pad 52; Carry out cut at point 53 places and form cut-out point 53.
B) electric signal of the breakpoint of data line 70 top will enter pcb board 63 by line segment 42, after the amplifier 64 on pcb board amplifies, then by line segment 44, be input to the below of array base palte.
C) again point 55 and point 54 places are carried out to laser bonding, form pad 54 and pad 55; At point, 56 places carry out cut, form cut-out point 56.
D) electric signal being input to below array base palte along line segment 44 will, by line segment 45, line segment 46, be input to the lower part of the breakpoint 100 of data line 70, thereby realize the broken string reparation of data line.
The IC left and right that two of tops of liquid crystal panel line segment 41 is adjacent does not connect, and only in each IC, connects, and for each IC, is the corresponding design in upper right, lower-left, as the IC1 to IC24 in Fig. 2, and all same design.Therefore when actual repair, simple, identification is high.
More than describe the preferred embodiment of the present invention in detail; but the present invention is not limited to the detail in above-mentioned embodiment, within the scope of technical conceive of the present invention; can carry out multiple equivalents to technical scheme of the present invention, these equivalents all belong to protection scope of the present invention.
It should be noted that in addition each the concrete technical characterictic described in above-mentioned embodiment, in reconcilable situation, can combine by any suitable mode.For fear of unnecessary repetition, the present invention is to the explanation no longer separately of various possible array modes.
